Justin Trudeau says he highlighted a number of consular cases every time he’s had the opportunity to sit down with Chinese leaders, including that of Kevin Garratt, a Canadian imprisoned for more than two years in China on espionage charges.

Trudeau has said in the past there’s no evidence to support the accusations against Garratt, but he didn’t say what China has told him about the case.

The lawyer for the Garratt family says they’re extremely frustrated by a lack of progress in securing his release.
